OK, I'm going to get grumpy here, sorry about that. Your comment is a perfect demonstration of middlebrow criticism, and adds exactly zero to the discussion.
Firstly, I'm Australian. We use SI measurements - your comment is not just smug, but wrong.
Secondly, are you honestly postulating that people understand the underlying reality of what a kilowatt hour actually means? That they have a "gauge" that can measure kilowatts? Of course they don't, and for that matter most people that use BTUs don't really understand what they represent either. They just know that it's a measurement of energy-use. All they really want is something that allows them to compare two options, and frankly, the units matter not at all.
